Bugfix: couples input pose to rawGraphicsRepresentation in VTC example.
Adds position & orientation scaling to NovintCommonDevice.
Fixes orientation scaling in NovintScaffold.

Scale the angles, not the rotation matrix.
Note that only the 7DOF provides an orientation to scale.
Adds mutex to protect the NovintCommonDevice scaling factors.
Adds missing doxygen signatures: NovintScaffold and NovintCommonDevice.
Removes unnecessary (potentially confusing) comments in NovintScaffold.
